Symposium S.NM12-Synthesis and Control of Dirac or Topological Materials

A long sought-after goal in materials science and condensed matter physics is the control of macroscopic quantum mechanical phenomena in systems known as quantum materials i.e. materials exhibiting emergent, non-classical properties. Notable examples include unusual quasiparticles in topological insulators, Dirac and Weyl semimetals, macroscale quantized transport phenomena, superconductors beyond the BCS paradigm, and emergent effects near quantum critical points. There are, however, many challenges–in particular, identifying intrinsic features amongst the complexities of materials systems that have defects as well as many competing interactions, and developing strategies to manipulate their materials properties. This symposium will highlight recent efforts among synthesis, characterization, and theory for the discovery and characterization of new phases of quantum matter. There will be a specific focus on routes to manipulate quantum materials: the use of dimensional and symmetry control in atomic-scale heterostructures and interfaces, external control via epitaxial strain, pressure, or applied magnetic or electric fields, revealing metastable states via intense photo-excitation, and theoretical efforts to predict and understand observed behavior.

Topics will include:

  • Synthesis of thin films and bulk crystals
  • Phenomena of strongly correlated and topological materials
  • Emergent phenomena in thin film systems through heterostructure control and strain engineering
  • Pressure and field-mediated control of macroscopic material properties
  • Computation, theory, and modeling of quantum states and phenomena
  • Data analytics and machine learning for quantum materials
  • Transport phenomena and devices
  • Spectroscopy and local probes of quantum phenomena
